Ailunce HD1 / RT29 Ham Radio Accessory Adapter (to K1 2-Pin)

Just what I needed for my Retevis RT29D radio. The dust cover is flimsy and likely to break off but it will still be functional.

Rendered my HD1 Useless after, what I assume is brass, snapped under barely any force. I was able to get it on prior and the connection is solid, even when modulating to different setups. Very disappointed in this, however.Update:Same day, used a knife to rotate the broken tip out and removed a screw from the HD1 Microphone, successful change and reinstall. I will not change my review seeing as if I didn't have a screw to replace it, I would just be buying another brass unit and waiting on it to snap under sub-optimal force. HD-1 Speaker mic uses a steel screw.

I have a lot of accessories for B-Tech radios and didn't want to have to invest in another set of proprietary accessories for the Retevis radio. This adapter took care of it and is solidly built.

The rubber on them rips off really easily. I had to tighten down really hard on the screw to get them completely flushed so that there is not a gap. I’ve had it more than once where I’ve plugged in the headset and it just doesn’t work unplugged replug then take off that side piece. Put it back on then it’ll start working. I don’t know what the issue is.

Works.... Screw it on, plug in a mic and it worked as advertised. Lets me use the Kenwood accessories I already had for other radios on my Retevis Ailunce HD2 DMR radio.

This thing cuts off unexpectedly. The Ailunce radio is not mature either. Save your money.

Works well

I bought the speaker mike for my Ailunce HA1G but I couldn't get it to connect right. I returned it and bought this adapter and it works great. Now I can use a regular two pin speaker mike.

Works as advertised. We can now have multiple base stations working in a small area and using a full noise cancelling headset.

Great product highly recommended

When attached the radio still passes audio. Once handheld mic is plugged in to the ports the audio ceases from the radio and comes through the hand mic.It would also be nice to have a version (or switch) where audio can come through the mic cable and the radio speaker simultaneously, especially when using an APRS cable so one could decode digital signals while still being able to hear voice communications.

20240907 - Update. Received a replacement from Retevis. This unit is working as advertised. I've only done initial operational testing and cannot speak to durability yet. If there are any issues with the unit I will update this review again. At this time I am changing my rating to three stars. While Retevis did replace the faulty product, it has taken over a month and a lot of back and forth.To their credit, Retevis did offer to replace the faulty unit and give a refund for the delay. However, I do not expect a company to provide a product free of charge and refused the refund.---------------------Original review follows-------------------While I am able to connect a kenwood style headset to the radio using this, the sound still plays through the radio. To be clear, even when a headset is connected the sound plays through the radio's speaker. This defeats the purpose of having a headset.Retevis customer service went back and forth with me for about two weeks. It is possible the language barrier played a part in that. I was told they would ship me a replacement and update me with a tracking number. Haven't heard anything since.Bummer because I really like the C1 radio, but I hate the headset that is offered with it. Looks like another HT that will be hanging out on a shelf.

works great

This is a perfect design that allows for the radio to be secured in a pouch without disrupting functionality of an external microphone/speaker.

Works exactly as designed. Adapts an HD1 to a kenwood.

I normally don't write reviews, but given that I was on the fence about buying because of some of the reviews, I thought I'd leave some comments that might be helpful to others.First, I can understand how some people ended up snapping off the connector screw while working with this. The adapter works fine on my RT82. I haven't had any issues with it yet as far as audio, though I just received it today. That being said, it is EXTREMELY tight to fit on. I'm assuming that maybe it's because it's made to fit many of their radios, so the fitment might be different on some of them, I don't know I'm just guessing. When you put this thing on though, at least on my RT82, you have to press it down very hard in order to get the screw lined up to begin tightening it down. The plastic tab at the top of the connector has a very extreme angle on it in comparison to other attachments for this radio. Due to the extreme angle, that plastic tab acts as a very rigid spring. While other accessories just slide nicely into place, and are then easily tightened down with the screw, this one has to be pressed VERY hard and held in place carefully while you line up the screw, and then of course ultimately tighten it down. This is hard to do because it almost requires 3 hands, but not so difficult that it's impossible. You just have to be very careful and patient, and hold it very steady while you apply pressure to get it in place with one hand, until you can start screwing it down with the other.All in all, it's not that bad, but yeah I can see how some people end up breaking it fairly easily. Just be careful, hold it very firm and steady, and it's fine. Aside from that issue, it does what it says and I can connect to my laptop via 3.5mm for APRS and I'm sure it'll work fine for other applications, headsets, etc.The only other thing I will mention is that although the description indicates that they did some sort of fix to allow audio to come through the speaker while this attachment is on but not in use, that was not the case with mine. I don't know if that depends on the radio you're using, or possibly firmware version? Again, I'm using this on an RT82 which it is listed as compatible with, but maybe whatever "fix" they did for that only works on the HD1, I have no idea. Either that or maybe I got one of the old ones they still had laying around. Who knows? Not a big deal for me really, because I won't be keeping this on regularly and really only want it for the APRS soundmodem connection. If I end up using it at all outside of that, it's almost certain that it would be to connect a headset, in which case I would just take the whole attachment off if I want speaker audio.

The Kenwwod pins work on all of my UV variants - but the pins will not fully seat in this Retevis adapter. I purchased one, and hooding that the first one was an anomaly, I purchased another. First one was the type that stops speaker from working when attached - the second one is this type, the one where even while attached you can use toy radio as normal. Neither of them allowed for proper seating of the Le wood plugs, causing very distorted reception on other radios.

Bought 24 of these for use with our security radios. Within 6 months, 7 have failed. It was necessary to remove all 24 items from service due to the necessity in having reliable equipment used in a security settings. I reached out to Retevis and they only offered to let me buy more at a 50% discount instead of replacing the faulty items are no cost. I can only assume that due to the known failure rate and cheap product that they only warranty these things for 30 days and aren't interested in product reliability.

This does "work" in that I can transmit and receive with any mic, but it adds a constant ticking noise to the mic speaker.

Bought this unit for my ailunce hd-1. Works as advertised. No issues with the pin configuration for my application. My only complaint is the screw that holds it down to the radio is just a tad on the short side. Works fine just a bit difficult to get it started. That aside everything works as advertised.
